Hello. Navigate to Backend > Comments.
1) Try press on "ID" or "Created date" column.
Result: page updated, but nothing happened.
2) find long comment. Press "More ..." – nothing happened
3) There is no link to commented item.
Admin want to check other comments at item page. Or want to check what exactly was commented.
For example user posted comment "I agree" – nothing criminal. But he commented item with text "We need to kill all unicorns". So may be comment should be deleted (and item tooo).
Thanks.
